The fact that each character in a Python string has a corresponding index number allows us to access and manipulate strings in the same ways we can with other sequential data types. Accessing Characters by Positive Index Number. By referencing index numbers, we can isolate one of the characters in a string. In python list is mutable, so the size is not fixed. Due to size is not fixed, the available index is greater than the assigned index for a list(available index Teams. Q&A for Work.
